Re errin to the drawings, which are mere g illustratlve of my inventiondetails are isclosed supplementing the disclosure of an invention'forautomatically and telephonical- 6o ly recording and conveymg messagesduring the absence of a telephone user. Reference will be made to a.copending application directed to the same physical parts butdescriptive particularl of the details concern- 5 ing closing thecircuit to the message conveying apparatus automatically. Herein it is 4proposed to disclose the details as they relate to t e manner in whichthe message is dictated for transmission locally to distant points andfor recording the messages locally impressed upon the same apparatus.

In practice, in a telephone box 11, mounted u on a post 10, are locatedthe bell clapper whose clapper stem B isdesigned to ring the bell A whenthe telephone is put into use in the conventional way. The means foroperating the clapper is through the lever E pivotally connected looselyand with lost motion permissible, to the clapper C as at 30 7 9m. Theupper end of the-lever E is pivotally connected to the armature 83having a ivotal movement upon the switch member W msulatedly connectedto box 11. An. electromagnet 18 is mounted in the box 11, as also is asa fixed contact member 25 having a binding post 26. A coiled spring 24is secured to the armature and to a point of the box and normally holdsthis armature in contact with two contacts 67d and 67, the armaturebeing divided into two circuit making portions 23. 83 by means of theinsulation 82. One of the line wires 19 is connected to magnet 18, theother wire 17 connecting to this ma et also connecting with binding post16 of t e trans- 'mitter box.

The other line wire 26 may be connected with binding post 15 if desired(not shown). The receiver 13 hangs upon its hook, and the transmitter 14is also disclosed. A battery 29 has a wire 28 running from one sidethereof to wire 27 to the contact 25. A knife switch handle 61 has itsblade engaged in the switch member W and this blade is pivoted toa'curved contact member 650 carrying a binding post 6503 with which theblade of the switch 61 may also engage. From binding post 6503 leads awire 21g to the other side of battery 29, and from this side of thebattery runs a wire 30 to a binding post 31 on a motor base M on whichis mounted a motor 35 having a shaft 36 carrying a pulley on which istrained a belt 37 which is also trained upon a pulley 38 on a main shaft39 journalled in a standard or upright 57. The other binding post 32 ofthis motor base has the wire 64 running to connect with contact post65a. A pair of oppositely arranged wax cylinders 40, 40a are mountedupon the opposite ends of the shaft 39.

A series of hook-shaped contacts 41 are provided and their shanks 43 aredesigned to be carried by collars 42a adjustably slidable upon a rod 42raised above the base M by means of the legs 43 secured to this base M.These contacts 41 are spaced apart at varying distances for the purposeof setting apart spaces therebetween upon which messages can be recordedupon the wax cylinder 40, longer messages requiring greater spacesbetween the contacts41.

A lever or pendant 55 is pivoted between its ends upon a pin 56 to theupright or standard 57, and at its ends respectively carries the pins 54and 54 designed to freely project in the slots 53 and 53 of hangers 52and 52' secured centrally upon rectangular frames 51 and 51a, theseframes providing tiltable bracket spiders. Mounted upon the lower rungof bracket spider 51 at the left of Fig. 1 is an operatively mountedtransmitter receiver 46, a similar device 46a being shown on the spider51a on the right of Fig. 1.

The recorder-reproducers 46 and 46a are adjustably mounted upon thebracket-spiders carrying them, the stops 49k, 97 and 100 limitingmovement of these members upon the spider. From contact post runs a wire89 to contact post 48a on the recorder-reproducer 46a, and from theother contact post 4911 of this member runs wire 90a and wire 21%: towire 21a, wire 21 to contact 15 via wires 21;), armature 23 and wire21c, and the adjacent contact 16 has wire 17 connected thereto whichruns to electro-magnet 18 from which runs the wire 19 as one of thetelephone line wires. 4 A wire 219 runs from contact post 65d oftheswitch 61'and connects with wire 30 running from one side of thebattery. W'ire 21e runs from contact 82 on contact ar1n'80b and connectswith wire 28 which runs to the other side of the battery; while wire 33runs from the other contact arm 81 to the motor 35 (see Fig. 3). Thewire 21d connects telephone 77 and wire 21c.

A wire 46m runs from wire 68 (see Fig. 6) to bindin post 46g mounted onstop 46h from which post Wire 467?. runs to post-contact 46, which isimmovably mounted upon stop 46h. Contact 467' is mounted u on a stemwhich projects through 46h. ontact 46 is mounted upon a stem whichprojects through a hole in 4671. being pressed againstrecorder-reproducer 46 by spring 462'. Wire 4670 runs from 46 to post4611 on rod 43. Means in common use with necessary modifications will beemployed to move recorder reproducer on the cylinders.

From binding post 66 runs wire 68 to binding post 80 on conductor 79 ofsolenoid 69 (see Fig. 7 Insulation 78 separates conductor 79 from arm ofplunger-armature 76. Contact arm 72 is insulated from support whichsupport is part of standard 88. Wire 680 runs from binding post 73 tosolenoid 69 from which runs wire 7 4] to wire 74d which wire connectswith contact 740 upon which rests contact 7 4?) when microphone 77 isresting on arm 805. From contact 7 40 runs wire 74eto 747- to bindingpost 74g, (see Fig. 4), contact 74 The circuit continues to conductorshoe 85, stem 87, wires 74m and 74 to battery 29.

From the battery 29 runs wire 30 to which is connected wire 690 whichruns to post a of solenoid 69a (see Fig. 4). Contact arm 79a isinsulated from arm plunger 76a by insulation 78a. Conductor arm 72a isinsulated from casing 7 0a from which casing extends also arm 84 whichsupports shoe 85, its stem 87 and spring 86 which presses againstplunger 76a. Wire 68b connects binding post 73a to solenoid 69a and wire74:; leads from the solenoid to wire 7 4e.

The magnets controllin the posts 6 and 7 6a are for the purpose 0lowering one end of the bracket-spider or teeter to depress onerecorder-reproducer to engage with one wax cylinder while the otherrecorder-reproducer is raised out of engagement with the other cylinder.

From the foregoing description the operation of the parts will now bedescribed.

When it is desired to record messages of varying character upon thecylinder 40,which is for transmitting messages over the phoneto partiescalling while a person is absent, the person talks intothe transmittinginstrument 77 the particular message it is desired to record upon thiscylinder. See that switch W is open and that switch 650 is closed. (Fig.1

Place recorder-reproducer 46 on the proper section of the cylinder 40,by lifting lever or frame 55, adjusting the stops 46k and 98 on thespider, and then lowering the frame 55 to place the needle 60 upon therecord cylinder 40. Take the receiver-transmitter 77 oil thehook 79 ofcontact lever 80b to allow the former to spring up automatically aganistcontact 801), and back to contact 81, as the latter has engaged contact806 when the receiver 77 was removed from its hook. The

I operator may then speak a message through receiver-transmitter torecorder-reproducer 46 as follows:

Hello, Blank and Company speaking. The oifice is closed now' as ourhours are from 9 a. m. to 4.30 p. m. If you cannot call up in themorning please leave your message.

The person calling thus receives this message, when central telephonestation establishes the connections properly. The present invention canbe efiiciently employed to record a conversation over the phone whilethe owner himself is phoning. In this event it will be necessary to pushdown the spider and frame 51a, to place the needle 60a in contact withthe adjacent wax cylinder a. Then switch W will be closed andarm'ature2383 depressed. This will close the circuit to the motor asfollows :While the distant telephone instrument is in use by one of theparties talk ng. current flows from one side of battery 29, through wire30, to motor 35, wire 64'. binding post 63, thence through closed switch61, armature 23-83, post 25, wire 27 and connecting wire 28 back to theother side of the battery 29.

The motor starts to rotate both cylinders and needle a, at the right ofFig. 1, begins to trace the conversation'upon the adjacent wax cylinder40a. When the conversation has been completed it will be necessary toopen switch 61 again. Y

The phone circuit for this operation is as follows: electro-magnet 18line wire 19, central operator,'distant telephone, central, line 7 wire26, wire 21], armature 23, wires 21p, 21, 21k. 90a, recorder-reproducer46a, wires 89' and 210, post 63, switch 61, armature 83, contact-post25, wires 27 and 216, post 16 and wire 17 back to magnet 18.

The method of hearing messages dictated to a wax cylinder 40a forrecovery by a stenographer or typist and for hearing messages receivedwhen the owner may not be present will now be described. See that theswitch W is open and 650 closed. 'Place receiver-transmitter 77 to theear and see that the needle 60a rests upon the wax cylinder 40a and thatthe post 49a rests against stop 100 (Fig. 1). This will'close the motorcircuit as follows:--The removal of instrument 77 from the contact arm80?) causes this contact 90a, 21, 21a, phone 77.

to abut contact 81; current flows from one side of the battery 29 bywire 30 to motor 35; thence by wire 33 to contact 81; thence by wire 21aand wire 28 back to the other side of the battery. The phone circuitbetween receiver-transmitter 77 and recorder-reproducer 46a is closed asfollows: phone 77, wires 21d, contacts 213 and 212?, wires 21d, 21c, 28through. battery 29 and wire 21g, switch 650, post a, wires 21c and 89',post 48a, recorder-reproducer 46a, post 49a, wires In order to dictatemessages for the typist using the invention as adictating machineproceed as described hereinbefore in connection with employing thereceiver-transmitter 77 to hear a recorded message. Be sure that theneedle of the recorder-reproducer 46a has been placed beyond the lastindented line on the wax cylinder 40a marking the end of the nextprevious message, which point is indicated by movable slide tab 101.Talk into the transmitter. 77 instead of applying it to the ear.

prospective calls see that switch W is open; close switch 650. Place thereceiver-transmitter 46 at the left of Fig. 1 in the correct position orsection of the record cylinder 40 so that its needle 60- wi'llultimately engage the proper hook contact 41, lifting bracket In orderto dictate messages in answer to frame 51 in order to effect thisresult. The

operation then proceeds in a manner already detailed hereiribefore, themotor circuit being the same. p

The phone circuit is as follows: phone 7 7 wire 21d, contacts 218 and21:7, wires 21d and 21a, 28, battery 29, wire 21g, switch650, post 650.,wires 21c and 89, post 48, recorderreproducer 46, post 49, wires 90, 21,21a and back to phone 77. From the foregoing it will be seen thatmessages may be heard 10- cally that are dictated locally.

It is understood that ordinary gears and worms, etc., from shaft 38willcontrol the movement 'of recorder-reproducer 46 and 46a upon the waxrecords.
